The Transition of Maile

[M. Val. Naso]

But we're talking about a fixed lining. Linen is not as flexible as mail is. So therefore if you fix it to the inside of the mail, two things can happen generally:

1. Linen (or leather) backing is tighter than the maximum extent of mail. Therefore the flexibility of mail is reduced.
2. Backing is fitted to the same size as the maximum extent of the mail when pulled out. It might compromise the mail's ability to contract, and also it would hinder comfort.

Or am I totally missing something?
